I found below error message in the Error log. it happened on the getattachment/[GUID]/[NodeAlias]?width=100px&100px. I believe it would be redirected to the getfile page to do the resize. I believe the error thrown because of the file size may be too big.

1. I wonder what is the file size restriction?
2. Could I change the limit?
3. How should I handle big image?
4. Any article would explain this in details?

Cheers,
Matt
